In this work, a new generation UV-transparent polymer, fluorinated ethylenepropylene
copolymer (FEP) exhibiting a low degree of crystallinity, extruded in dimensions similar to
the most commonly used CE capillaries of ,80 mm id and about 360 mm od was investigated
for its use as a CE capillary. FEP is transparent down to the low-UV region, and as
fluorinated polymers in general are good electrical insulators and exhibit reasonable heat
conductivity, it has considerable potential as a material for electrodriven analysis in capillary
or microchip formats. The FEP capillary has been characterised with regard to some
important aspects for its use as a CE capillary, including its profile of EOF versus pH, as well
as procedures for manipulating EOF by coating the inner capillary wall with various semipermanent
and dynamic layers. The FEP capillaries were tested and compared with fusedsilica
capillary for the separation of inorganic and small organic ions using conditions involving
direct and indirect detection in the low-UV region. Finally, advantages of the use of
the FEP capillary for simultaneous detection of a mixture containing nine inorganic cations
and anions using indirect photometric detection with a movable light-emitting diode (LED)
detector and a novel electrolyte are demonstrated.
